Both of my setups are still running fine. When done do they just stop?
Or do I have to somehow guess when it is 'slowing down'? My 3 Liter bottle has this real nice continuous tiny bubble stream going and the tinier the bubbles I assume the better the absorption.
The Nutrafin ladder is still going. Not like crazy, but still going.
So, how do you know when to 'recharge' ? |
